Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose. This standard provides the acceptance criteria and repair procedures for weld-through sealer(s) in automotive products for which GM is responsible for establishing or approving product design. 1.2

Applicability. This standard applies to any application where a weld-through sealer(s) capable of being pumped at ambient temperatures and intended for use in the body shop is used to seal body joints against water, dust and air intrusion.

The criteria established in this standard become mandatory when referenced in product release information or an approved Product Quality Standard (PQS) document. Deviations from any sealer criteria provided in this standard must be identified in product release information or an approved PQS document.

Usage. Weld-through sealed structures are considered satisfactory when they provide leak-free seams in identified water paths, and prohibit water intrusion to meet corrosion requirements for a required period. Corrosion requirements in structures containing "weld-through" sealer in a vehicle are varied in both type and magnitude and cannot be addressed by this standard. Therefore, while the sealer quality criteria of this standard are consistent with service requirements, they have been established specifically for use in process and product monitoring. Any attempted application of this document to other uses may lead to an erroneous result or conclusion.

Clarification. For clarification of this standard or editorial comments, email the GM Weld Council at: [email protected].

Proposed changes to this standard must be presented to the Global Weld Council. To suggest a change to this standard, reference the "Procedure for Weld Standard Changes" on the Weld Council's web page.
